WINDOW-SASH HOLDER.

iippiivaiion inea January e', 1927. seriai No. 159,307..

My invention .provides an improved sash holder for supporting slidingsash in various diiferent adjustments, and, generally.

stated, the invention. consists of the novel devices and combinations ofdevices hereinafter described and definedin the claims.

ln the accompanying drawings, which illustrate the invention, likecharacters iiidicate like parts throughout the several views.

Referring to theA drawings: j Fig. -1 is a fragmentary view inelevation,

looking at the inside of a wifndowhframev and.y sash, the vlatter beingheld by friction supports designed in accordance with what is believedto be thel preferred form of the invention; y f

Fig. 2 is a section on the lineL 2-2 of Fig. 1;

Fig. 3 isa fragmentary view partly in elevation and partly. vinverticalsection showing in detail the structure of the frictionalholderillustrated in Figs. 1 andf2;

'Fig'. 4'- is a horizontal section on the vline .Fig 5 is aperspectiveshowingthe;ele# ments oftheholderin Figs. l, 2, 3 and 1segregated ordrawn apart, some parts being Fig. 8 is another viewcorresponding vtof Fig. 3 but illustrating a still further modifiedconstruction g and 9v is a section taken ontheline 9-9 l .of Fig. 8,lthe window-v frame `being removed.

i Describing first the structure illustrated in Figs. 1 to '5,inclusive', 'the numeral 10 indicates a window vframe of the'usualconstrue` tion ,except that weight boxes are not'proj4 vided, the samevframe being, as Vshown in Fig. 2, set into a wall 1 1. The framelO-hasthe customary inner and outerl sash-guiding channels 12 andl,respectively, inl whichl work slidably lower'and upper. sashes 14y and15, respectively. y The guide channelf12, as show-n, is formed betweenan `intermediate stop strip 16 andan inside stopstrip 17, and the guidechannel 13is formed between said intermediate4 Strip 16 land -an outsideguide are preferably removable. f

strip18. rlhe strips 16 and 17, as is usual,

Thefriction device for supporting the two sashes are alikeand hence thedescription o f one `will answer' for the description of the other. 3 'iThe main supportingielement of the friction device is a smooth rod 19providedat its upper end withI a head 20 which, yby a screw 21 or thelike, is pivotally anchored tothe window Vframe within the vcorrespond-`ing sash-guiding channel. This iod 1,9 Works freely through perforatonsinthe arms of Aa a inortise 23 formedin the adjacent edge of the sash,as best'shown in Fig... 3. TheVV inortise 23 holds the friction head 22for travelling movements with thesash but per'- init-s it to movesuiiiciently to adjust itself to the rod 19.

. lVoiking within the openingY of the friction,

head 22 and between rvthe uppeifffan'd.lower. armstliereof is awedge-shaped friction` block `yoke-shaped friction head 22 that is setinto i 24, theouter edge .of which isfgrooved Yto lit the` rodI 19andtheinner edge of which is as shown in the preferred 'forni issupported by the Vcurved free end of av iexible strip of metal 25whiclnat its other end,is anchored to the friction head by a. rivet 26or the like. The free' end' of this flexible abutimantV is engaged byanfai'ljusting screw 27 that Works through. the back ofthe friction head2 2 and is adapted to be reached for .adjustment 4by a screw driverinserted through la `hole28 formed in the sash` As shown, the screw 27is held against accidental movementsbya split.

spring washer`27n. A coiled spring 29, placed around the rod 19 andcompressed between thelower arm ofthe head 22 and the lower end ofthewedge-shaped friction block 24,

loblique and is seated against the abutment carried by the frictionhead. This abutment A'80. i

yieldingly presses the latter upward-so that it will be `lightly wedgedagainst 'therod 19 and the abutment 25 and .willinstantly grip the rod19 when theV sash 15has beenraised toany desiredheight. VThe adjustmentof the sash is being raised or when the-weight of Y10o Athe screw127will usually besuch that, when the sashisrelieved.fromthe frictiondevice,
